Hello Mobile customer service phone number disconnected

I am trying to port out my lines from Hello Mobile. Their website has always been basically useless for reaching customer service via chat, so I would really like to call them, but nope. “Your call cannot be completed as dialed. Please check the number and dial again.” I’m calling the only number on their website, 1-888-95-HELLO. Do they have a new number that they’ve just not yet put on the website, or am I out of luck here?

Edit: Finally got a rep via chat on the website. Porting out actually happened shockingly fast once I got the port blocks removed. Both lines are now ported out, and my Hello Mobile nightmare has finally come to a close. Porting to Total Wireless, I selected StandUp as the carrier, and it was actually smart enough to not ask me for the transfer PIN (last 4 of number). Impressive!
